ELMER sTRo'NG'AND HOMER TARBUTTON, or MANsFIELD mssounnhssmnons or ONE-FOURTH T0 FRANK L. BEACH Ann ONE-FOURTH "ro mocAnTEn; BOTH 0F MANSFIELD,- MISSOURI} To all whom it mag/concern:

' Be it known thatwe, VELMER Srnone'and Horns TARBU1TON," citizens. of the llnited State's, residing-j at. Qlfiansfield, l'llr ght County, h/iissourn have invented a new and useful-Emergency Axle, of which the followingis a specificatlon.

V This inven 0n-relates to emergencyaxles.

' An object of the inventionis-to prov de a device adapted to jbe used asan. emergency axle for attachment of the wheel to a broken axle of an automobile orthelike,

Another object of the-inventionis to pro vide a deviceof the-character andfor the purpose mentioned, having novel and" improved means i'or' connection w th the end of a broken axle.

Other objects will -following description, reference being niade to the accompanying drawing-LinwhiclP- 1 Fig. 1 is a view; withv a )a'rt inf section e I l showing device attachedto a broken: axle.

Fig. 2 is a cross-sectional view on'the line 2+230Fg1h ig. 3 iscross-sectional-V ewonthelrne Fig. 4'': is a. sided-elevation of-one of the keys by which. the d'ev celsf locked, or

- clutched on the broken axle,

;Fig..,5 isan. inner side view .ofgthe key. As-shownin Fig. 1, the usual axle rhas been broken off at orneara point at which" the outer ends or the roller bearing elements operate It is usually at this point that the axle breaks, especially in Ford automobiles, dueto the fact that the {axle becomes crystallized or otherwise damaged.

- Our present inventlon comprises a device adapted to beattached to the broken .end

of the axle, and-embodying means for connection with the usual wheel of the auto 1 mobile whereby :the'automobile may-'jbe op-,

*eijated in the usual waywithbutfthe.he;

cessity of'being'to'wed. 1"

As shown, our device comprises-a memQ beriincludingja shank 2 extending into the hub of a wheel of the automobile and keyed I to the wheel by a key 3; The outer extremity 4 of the shank 2 is threaded to receive a nut 5 by which the wheel is held in place; .From the inner end of the shank 2 a cylindrical part 6 extends. The part 6 is of larger diameter than the diameter of the inner end of the shank 2 and, at its inner end, is formed with a larger cylindrical part connect d to the broken i axle of the lauto axle.

Specif cation of Letters Patent. Patent d A 4 5, .iAppliea tion filed August (19 211, H i H i 7, adapted to fill the.space. within theaxle houslng, taking the place ofthe. roller bearing. which -is removed. when this device'fis applied to the axle 1 y The cylindrical part 6.7fis. hollow so as to receive the end of thejbroken---axle,J-as shown in Fig. 1. The cylindrical part 6fis formed with a number; of longitudinal slots 8 extending inwardlyfrom the outer end. of said part 6, and continuing -as grooves '9 on theinner side ofthe part 7 As-shownth'ere' are three of the slots8although the num:

ber may be varied,"as desired. i The keys by which the emergency axle'is lockedv or, clutched in connection with the end of the broken axle of thej aut'omobile,

are placed; within the, slots, 8,: and en aged" in the. grooves 9 in the large cylindrical aartffi .IAs "shown each .key includesan elongated {body 10.,havii1g a beveled inner end 11 adapted to extend-into the groove-9 extending from the -,slot 8' in whichthe'key; is'placedr, Th'einnerside of each key-is provided with awedge point.l2flfor better engagementfwith the broken axle. Ashoulkey. A ring 1a is placed around the outer ends of the keys 10,:the innerendofthe' ring engaging the outeri-edgesof the shoulders 13;. The l Liis engagedbygthe washer 15; so that whenthe wheel-is placed on the shank 2 and the -n'ut;5. is. turned, the wheel will be I forced inwardly onto the shank, thereby forcing the l4 inwardlyand causing theringtozforce the 'keyslO inwardly asuflic ient distance to locker clutch the emergency; axle device in ,,connec der 13 is formed onlthe'outerisidesofeach tionwith the broken axle. -The edges-12 0r- 7 the keys engage insroughstops .or irregularlties on :the peripheryof :the broken axle and thus clamp: the emergency axle rigidly in: position. I j

y In pr fcticeiwe have found d ed;

vice accomplishes all of; its ;intended, pur posesf Thel emergen'cy axleflmay, be; easily mobile and, as an incident to the forcing of the wheel on the emergency axle,t he locks ingandclutching devices are adjusted to ,efiect rigid engagement with the broken axle. It is then impossiblefor the emerf gency axle to turn relative'to the broken.

of the device without departure from the nature and principle thereof.

We do not restrict ourselves to unessential features but what we claim and desire to secure by Letters Patent is v 1. An emergency axle, comprising a shank v adapted to fit within the hub of a wheel, a

key arranged to interlock with said shank and with a hub of a wheel on said shaft, a hollow cylindrical part extending from the inner end of the shank adapted to receive the end of a broken axle and having longitudinal slots therein, an enlarged cylindrical portion rigid with the inner end of said cylindrical part having grooves in its inner side in continuation of said slots, and keys adapted to be located in said slots to form clutching engagement with the broken axle.

2. An emergency axle, comprising a shank adapted to fit within the hub of a wheel, a

'holloW cylindrical part extending from the inner end of the shank adapted to receive the end of a broken axle and having longitudinal slots therein, an enlarged cylindrical portion rigid with the inner'end of said cylindrical part having-grooves in its inner side in continuation of said slots, keys adapted to be located in said slots to form clutching engagement with the brokenaxle, and a device for clutching said keys in engagement with the broken axle.

i 3. An emergency axle, comprising a part adapted to be'secured in the hub of a wheel,

a key arranged tointerlock with said part andwith a hub of a wheel on said part, an integral cylindrical part adapted to receive the end of a'broken axle and having longi 'tudinal slots therein, clamp members adapted to be located insaid slots to engage the broken axle, and a ring for binding theclamp members in engagement with the broken axle and arranged to be forced 'to binding position as an incident to the placing of a Wheel on said part.

4. An emergency axle, comprising a part adapted to be secured in the hub or a wheel, a key arranged to interlock with said part and with a hub on a wheel on said part, an integral cylindrical part adapted to receive the end of a broken axle and having longitudinal slots therein, clampmernbers adapted to be located in said slots' to engage'the broken axle, a ring for-binding the clamp members in engagement with the broken axle and arranged t0v be forced to binding position as an incident tothe placingof a having grooves for receiving the ends of said clutch members, and a removable ring embracing the outer ends of said clutch members.

6. A device of the character described,-

comprising a hollow cylindrical part, having longitudinal slots therein, a ring integral with the inner end of the cylindrical part having grooves therein in continuation'or said slots, a clutch member located in each groove and extending into the corresponding slot in the ring, a radially extending shoulder on each clutch member, and a ring removably encircling said cylindrical part and the outer ends of said clutch members and bearing against the outer'edges of said shoulders. Y l

7. A device of the character described, comprising a Wheel supporting member, a cylindrical part integral with said member adapted to receive the end of a broken axle and having longitudinal slots therein, removable elutch members located in said slots, a ring integral With the inner end of said cylindrical part, holding the ends of said clutch members pressed against the axle, radial shoulders on said clutch members, and a removable ring encircling said removable part and the outer ends of-said clutch members and bearing against said shoulders, holding said clutch members pressed against the axle. V

8. A device of the character described, comprising a'wheel supporting part, a hollow cylindrical part integral with the wheel supporting part and having longitudinal slots therein, a clutchmember located ineach of said slots, each of said clutch members having a: wedge-shaped inner portion adapted to engage'the periphery of an axle
